>>1009765I was making a dumb joke. There's nothing wrong with reusing old spokes.
Yes, Off Set Bead is the zig-zag pattern. With your rim though, the pattern isn't wide enough to matter, you can treat it as 0 offset.
>>1009771are you using the proper tool (pictured) or are you just eyeballing the hanger? Because you really need to the tool to check alignment relative to the wheel - the trick is to use the tool to find the high/low spot (indicator) relative to the rim, bend the hanger a little, check again, bend, check, bend - repeat until the hanger is perfectly aligned with the rim no matter what angle you check at. With some practice you'll get good at doing this.
>>1009786The 'KOPS' system is a guideline for fitting road bikes, not an absolutely rule, and we can't diagnose your fitting issues without seeing you on the bike. You might conceivably need a zero-offset seatpost, but that depends on your frame and the way you ride. As for that post being turned around, you can try but I don't think it has enough range of saddle angle adjustment to work.
